The present invention generally relates to the knowledge and knowledge of connectivity between computing devices. More specifically, the present invention relates to a method and system that enables two or more computing devices to be connected together via a high speed wireless bus.

The digital revolution, which has been led by widely available computing devices, is now well under way, and a second wave is now taking place. The second wave includes improved interconnection of the various usable computing devices because users want an improved mobility and / or less disruptive experience. For example, conventional desktop PCs can provide a lot of usefulness. However, users typically have to stay in place not only because of the size of the machine, but also because of their various wired connections.

Many handheld and small profile computing devices now offer users significant computing power and flexibility. This flexibility is achieved by connecting to various services in a wireless manner, thus freeing up movement. For example, cellular phones, PDAs, notebook computers, and other devices can communicate wirelessly and are mobile. For this reason, this is becoming more and more widely accepted, especially when mobility is important.

However, mobile devices often inherently lack computing power and memory resources to perform complex applications in various environments. For example, a mobile device may employ customer resource management (CRM) and other business applications that require significant amounts of computing resources to perform sufficient front-end processing that provides a good environment for users to expect to be customized. Often not used in performance. Other applications rely on operations that provide a multimedia environment and / or require a lot of work by the processor. Such applications cannot currently be executed by mobile devices due to extended input / output requirements such as video and / or audio and multi-monitor usage. Therefore, there is a need to find new ways for users of mobile or other devices to experience this good application environment.

The following provides a brief summary of the present invention to provide a basic understanding for the reader. This summary does not limit or limit the outline of the invention. This Summary is not intended to identify key and / or essential elements of the invention, to delineate the scope of the invention, or to limit the scope of the invention in any way. Its sole purpose is to present some of the disclosed concepts in a simplified form as a prelude to the more detailed description that is presented later.

Embodiments of the present invention address the drawbacks of the prior art by enabling the connection of at least two computing devices over a high speed wireless link. In an embodiment of the invention, the resources of the devices are shared so that when the devices are connected it appears to the user as if it were a logical computing entity.

In one embodiment of the invention, a mobile host computing device is connected to a fixed host computing device using a high speed wireless link. This link can be established with a high-speed wireless bus that connects to the front bus of each device's CPU. This allows for the expansion of some computing resources such as one or more volatile memory resources, nonvolatile memory resources, and host processors. Wireless links are not visible to higher layers such as operating systems and users. In this way, a host is presented to the user as a logical host that includes the available resources of multiple physical devices.

Further features and advantages of the present invention will become apparent from the following detailed description of illustrative embodiments which proceeds with the accompanying drawings.

While the appended claims specifically illustrate the features of the invention, the invention and its advantages will be best understood from the following detailed description taken in conjunction with the accompanying drawings.

In general, the present invention relates to connectivity between at least two computing devices using a high speed wireless link. In an embodiment of the present invention, a wireless link enables access to one or more volatile memory resources, nonvolatile memory resources, and available resources of a computing device, such as a host processor. In a preferred embodiment, the high speed wireless link is invisible to higher layers such as operating systems and users. In this manner, the host computing device appears to contain the available resources of multiple physical devices.

As used herein, the term " high-speed connection " refers to a connection and is preferably sufficient to accommodate a data transfer rate that enables an interface with a processor located at the computing device. Refers to a wireless connection with bandwidth. For example, this term may refer to a wireless connection to the front side bus of a computing device.

1 illustrates one embodiment of the present invention. This embodiment establishes a single logical host computing entity 10 from the fixed host computing device 12 and the mobile host computing device 14. In FIG. 1, fixed computing device 12 is shown as a desktop PC. Mobile host 14 is shown as a pen-based mobile computing device. However, those skilled in the art will appreciate that a computing device may be implemented in any manner.

If the devices are located in relatively close proximity, the mobile host 14 establishes a wireless bridge connection with the fixed host 12 via the high speed wireless link 16. As will be described in more detail below, the wireless link 16 is preferably made via Ultra Wideband (UWB) wireless communication technology due to the amount of bandwidth available through the medium. While UWB is the presently preferred embodiment, it will be appreciated that the techniques described herein may also be used with respect to apparatus implementing other communications techniques. In fact, recently developed wireless communication technologies with dominant performance characteristics will emerge in the future. Such recently developed technology should be considered equivalent or structural equivalent to the UWB communication technology described and disclosed herein.

As described below, the high speed wireless link 16 shown in FIG. 1 bridges the front or equivalent bus of each of the computing devices. In this way, one device can access key resources of another device, such as another device's processor, volatile memory, and nonvolatile memory. In this way, the wireless bridge provides a virtual back-plane that provides instant access to the available resources of the computing device.

In the preferred embodiment, after the high speed wireless link is established, the operating system of one of the host devices (mobile host 14) determines the available resources of the connected device. This available resource is then extended to the mobile host device 14 to create a logical host with expanded processing power and / or memory capacity. In this embodiment, the operating system of the mobile device performs tasks such as memory management of the extended logical host, segmentation of task allocation between processors, management of bandwidth issues between processor and memory resources, and similar tasks. In this embodiment, the front side bus and wireless connection are seen by the mobile host's operating system as a single virtual entity.

In an alternative embodiment, after knowing about the presence of connections and additional resources, the operating system for the mobile host allocates resources by accounting for wireless channel bandwidth considerations. In this embodiment, the wireless host operating system may optimize the scheduling of available resources based on the bandwidth limitations of the wireless channel. The operating system may include the ability to balance bandwidth availability and resource availability of the wireless channel. For example, some tasks may be much more efficient to be performed by a wireless host processor due to wireless connection bandwidth. Or, depending on the file size and resources available to send data between mobile and fixed host computers, fixed host computer processors may be better equipped to handle processor-intensive tasks such as creating bitmapped images, etc. Can be.

2 shows another embodiment of the present invention. In this embodiment, the first computing device, shown as fixed host PC 22, is connected to mobile host computing device 24. In this embodiment, a high speed wireless link 26 is established between the computing devices 22, 24 via the hub 28. Hub 28 provides an access point that operates to coordinate high speed wireless connections by managing data traffic between computing devices 22 and 24. This configuration is particularly advantageous when other UWB devices such as wireless monitors, printers and other peripherals are present near the location of the hub 28. Once the wireless communication bridge is established, the operation is the same as described above in conjunction with FIG.

As mentioned above, the presently preferred embodiment of the present invention is described herein by referring to UWB wireless communication technology. UWB is often referred to alternatively as an impulse, baseband or zero-carrier technology. UWB is a wireless communication technology that transmits very short ultra-low power radio signals over a wide frequency spectrum. The UWB receiver can convert the received burst by recognizing the particular pulse sequence sent by the transmitter. The FCC has defined UWB to include any signal that occupies more than 500 MHz or has a fractional band of 20% or more, from 3.1 GHz to 10.6 GHz. The bandwidth of the UWB signal is typically about 25% of the center frequency. For example, a “2 GHz” UWB signal may have a bandwidth of 500 MHz.

The allowed spectrum for UWB is 7500 MHz. This is actually larger than the spectrum for other technologies currently in use. For example, an ISM of 2.4 GHz covers the 83.5 MHz spectrum and a U-NI of 5 GHz takes up to 300 MHz (to be increased to 500 MHz).

The output of the UWB signal is typically low. For example, the UWB signal may be about 1000 times lower than what is currently used for Wi-Fi RF transmission. Low power requirements are achieved through the fact that UWB signals are easily detected, i.e., signals can be easily extracted from background noise.

The modulation technique used for UWB is typically binary phase-shift keying (BPSK). In BPSK, each pulse is transmitted at 0 degrees or 180 degrees, ie on the right side or upside down. Thus, BPSK modulation is efficient when it uses the spectrum, which requires about half of the bandwidth of a comparable pulse position modulation system.

There are two approaches to UWB that are currently proposed. The single band approach proposes the use of the entire 7.5 GHz as one carrier. The multiband approach segments 7.5 GHz into the same channel. The basic premise is that multiple frequency bands transmit multiple UWB signals simultaneously, effectively utilizing the UWB spectrum. The signals do not interfere with each other because they operate at different frequencies within the UWB spectrum. Each of these signals may be transmitted simultaneously to obtain a high data rate or may be used as a means of multiple access to allow multiple users to communicate simultaneously. Several standard digital modulation techniques may be present in each UWB signal. The result of the modulated UWB signal can be added together before transmission.

Multiband UWB system designs are more scalable and adaptive than single-band designs, and are more capable of coexisting with systems such as 802.11a and lower risk (because this improves more traditional wireless design techniques). It has many advantages such as implementation. These benefits can be maintained while maintaining the same complexity and power consumption as a single band design.

With regards to scalability and adaptability, the advantage of the multiband approach is that, for example, low bit rate systems can use very few bands and high bit rate systems can use many bands. Another advantage is that it is probably adaptable to different radio regulations around the world in the absence of the same coincident spectrum allocation as occurs for the 2.4 GHz and 5 GHz used in WiFi and Bluetooth.

With regard to coexistence, another advantage of the multiband approach is to increase the level of coexistence with other services such as IEEE 802.11a. The receiver can dynamically adjust in-band interference by removing the affected band, and the transmitter can avoid transmitting in bands already used by other services in close proximity.

Finally, because the multi-band technology is based on known wireless communication schemes modified for use with the UWB spectrum, the technology provides a lower implementation risk. This makes multiband the best candidate for commercial applications that require multiple vendors and standard technologies for high volume adaptation.

Multiband systems allow the adaptive selection of bands to provide good interference robustness and coexistence properties. When the system detects the presence of an 802.11a system, for example, this may avoid the use of a band centered at 5.35 GHz or 5.85 GHz. This same feature can also be utilized to provision different spectrum allocations outside the US. Bands that share spectrum with extremely sensitive systems can be avoided.

Single band UWB systems need to employ notch filters to achieve the same result. Notch filters are not an ideal solution because they either increase the noise figure of the receiver or require a higher performance low noise amplifier. The problem with notch filters is that they are not adaptive and need not be realized with off-chip dedicated hardware. Also, in most cases, the notch filter incorrectly amplifies the received pulses, making it more complex to compensate for this result.

The invention is shown as being implemented in a suitable computing environment. Although not required, the invention will be described in the general context of computer-executable instructions, such as procedures, executed by a personal computer. Generally, procedures include program modules, routines, functions, programs, objects, components, data structures, etc. that perform particular tasks or implement particular abstract data types. Those skilled in the art will also appreciate that the present invention may be practiced in a variety of computer system configurations, including hand-held devices, multiprocessor systems, microprocessor-based or programmable consumer electronics devices. The invention may also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules may be located in both local and remote computer storage devices. The term computer system may be used to refer to a computer system as seen in a distributed computing environment.

3 illustrates an example of a computing system environment 300 suitable for implementing the present invention. The computing system environment 300 is just one example of a suitable computing environment and is not intended to suggest any limitation as to the scope or functionality of the invention. Computing environment 300 should not be construed as having any dependencies or requirements with respect to any one component or combination of components shown in example operating environment 300. While at least one embodiment of the present invention includes each component shown in the exemplary operating environment 300, another more typical embodiment of the present invention is necessary, such as input / output devices, for example, in addition to those required for network communication. Some or all of these components can be excluded.

One example system implementing the present invention includes a general purpose computing device in the form of a computer 310. Components of the computer 310 include, but are not limited to, a system bus 321 that couples various system components, including the processing device 320, the system memory 330, and the system memory to the processing device 320. As described in more detail below, the system bus 321 may be any of several types of bus structures, including a memory bus or a memory controller, a peripheral bus, and a local bus using any of various bus architectures. .

Computer 310 typically includes a variety of computer readable media. Any medium that can be accessed by the computer 310 can be a computer readable medium, and such computer readable media includes volatile and nonvolatile media, removable and non-removable media. By way of example, computer readable media may include, but are not limited to, computer storage media and communication media. Computer storage media includes volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information such as computer readable instructions, data structures, program modules or other data. Computer storage media includes, but is not limited to, RAM, ROM, EEPROM, flash memory or other memory technology, optical disk storage or magnetic storage, or any other media that can be accessed and stored by computer 310. It is not. Communication media typically embody computer readable instructions, data structures, program modules or other data, and convey all information, in a modulated data signal, such as a carrier wave or other transport mechanism. Media. The term " modulated data signal " means a signal that has one or more of its characteristics set or changed such that information in the signal is encrypted. By way of example, communication media includes, but is not limited to, wired media such as a wired network or direct wired connection, and wireless media such as acoustic, RF, infrared, or other wireless media. All combinations of the above described media should also be included within the scope of computer readable media.

System memory 330 includes computer storage media in the form of volatile and / or nonvolatile memory, such as ROM 331 and RAM 332. As an example, FIG. 3 shows, but is not limited to, an operating system 334, an application program 335, other program modules 336, and program data 337.

Computer 310 also includes other removable / non-removable, volatile / nonvolatile computer storage media. By way of example only, FIG. 3 shows a hard disk drive 341 for writing to or reading from a non-removable, nonvolatile magnetic medium, a magnetic disk for writing to or reading from a removable, nonvolatile magnetic disk 352. Drive 351, an optical disk drive 355 for writing to or reading from a removable, non-volatile optical disk 356, such as a CD-ROM. Other computer storage media that can be used in the exemplary operating environment include, but are not limited to, magnetic tape cassettes, flash memory cards, DVDs, digital video tapes, solid state RAM, solid state ROMs, and the like. Hard disk drive 341 is typically connected to system bus 321 via a non-removable memory interface, such as interface 340, and magnetic disk drive 351 and optical disk drive 355 are typically interface 350. Is connected to the system bus 321 by a removable memory interface.

The computer system may include an interface to an additional type of removable nonvolatile storage device. For example, the computer may have a USB port 353 capable of recognizing a USB flash drive (UFD) 354 or an SD card slot 357 capable of recognizing a Secure Digital (SD) memory card 358. have. USB flash drives are flash memory devices that are fitted to a USB connector so that they can be inserted into USB ports of various computing devices. SD memory cards are stamp-sized flash memory devices. Both USB flash drives and SD cards offer a lot of storage and high data transfer rates in a small package. Other types of removable storage media can also be used to implement the present invention.

The drives and associated computer storage media shown in FIG. 3 and described above store computer readable instructions, data structures, program modules, and other data of the computer 310. In FIG. 3, for example, hard disk drive 341 is shown to store operating system 344, application program 345, other program modules 346, and program data 347. Note that these components may be the same as or different from operating system 334, application program 335, other program module 336, and program data 337. In this regard, the different numbers given to the operating system 344, the application program 345, the other program modules 346, and the program data 347 show that at least they are different copies. A user may enter commands and information into the computer 310 through input devices such as a keyboard 362 and a pointing device 361, commonly known as a mouse, trackball, or touch pad. These and other input devices are often connected to the processing unit 320 through a user input interface 360 coupled to the system bus, but by other interfaces and bus structures, such as parallel ports, game ports or universal serial bus (USB). May be connected. A monitor 391 or other type of display device may also be connected to the system bus 321 via an interface such as a video interface 390. The monitor 391 may also be integrated into a touch screen panel or the like. Note that the monitor and / or touch screen panel may be physically coupled to the housing in which the computing device 310 is included, such as in a tablet type personal computer. In addition, a computer such as computing device 310 may include other peripheral output devices such as speakers 397 and printer 396, which may be connected via output peripheral interface 395 or the like.

Computer 310 may operate in a networked environment using logical connections to one or more remote computers, such as remote computer 380. Remote computer 380 may be another personal computer, server, router, peer device, or other network node, and typically includes most or all of the components described above with respect to computer 310, but FIG. Only memory storage 381 is shown. The logical connections shown in FIG. 3 include a LAN 371 and a WAN 373, but may include other networks. For example, in the present invention, computer 310 may include a source machine to which data is transferred, and remote computer 380 may include a destination machine, such as a thin client device. Note that the source and destination machines do not need to be initially connected by the network, but instead data can be transferred via any medium that can be written by the source platform and readable by the destination platform or platform. For example, one non-limiting example of such a medium is a removable flash memory medium.

When used in a LAN environment, the computer 310 is connected to the LAN 371 via a network interface or adapter 370. Computer 310 also includes a modem 372 or other means for establishing communications over WAN 373. Modem 372, which may be internal or external, is connected to system bus 321 via user input interface 360 or other suitable mechanism. In a networked environment, program modules described in connection with the computer 310 or portions thereof may be stored in a remote memory storage device. As an example, FIG. 3 shows, but is not limited to, a remote application program 385 residing in memory device 381. It will be appreciated that the network connections shown are exemplary and other means of establishing a communications link between these computers may be used.

While FIG. 3 generally shows details of the computing environment, FIG. 4 is a simplified block diagram of certain hardware components where a motherboard of a conventional PC or similar computing device is typically located. In the embodiment shown in FIG. 4, the fixed host 12 includes a CPU 410 that is connected to the NorthBridge integrated circuit 412 via the front side bus 414. NorthBridge 412 is generally mission-critical, such as handling requests for data transfers from RAM 416 and data transfers to RAM 416 as well as data transfers between CPU and AGP 418. ) Process the task. Thus, NorthBridge 412 includes a memory controller and associated hardware to effectively manage data movement between the processor, memory module, and AGP.

The front side bus 414 operates at a relatively high clock speed, allowing the CPU to access various resources of the system without going idle when data is transmitted. For example, the front side bus 414 can operate at a speed of 800 MHz, which translates into a peak data bandwidth requirement of 4.2 GB / sec. For this reason, the presently preferred embodiment of the present invention employs UWB technology. However, because other high speed radio technologies are being developed, other techniques may also be utilized in the present invention.

In addition to managing data transfer between the CPU and RAM, the NorthBridge 412 receives data and transmits data with the SouthBridge IC 420 over the SouthBridge 420 and a high-speed link between them. SouthBridge typically functions to provide support for a variety of input and output devices with different bus speeds and designs. For example, SouthBridge communicates with Interface Drive Electronics 422 to provide access to mass storage devices.

SouthBridge may be coupled with a LAN interface 424. SouthBridge also connects to PCI bus 426 to allow expansion cards to be added to a fixed host. SouthBridge 420 also supports serial port 430 as well as audio output 428. Finally, SouthBridge 420 provides an interface to BIOS software 432. However, because SouthBridge does not perform the core tasks of NorthBridge, SouthBridge does not require the data transfer rate of NorthBridge.

The mobile host 14 may be configured similarly to that shown in the embodiment of FIG. 4. As with the fixed host, the mobile host 14 includes a CPU 450 connected to the NorthBridge IC 452 via the front side bus 454. NorthBridge 452 also provides a high speed interface to graphics port 454 and RAM 456. As with a fixed host, NorthBridge 452 is connected to SouthBridge 458 in a high speed connection. SouthBridge 458 allows various internal and external peripheral components such as IDE 460, FireWire port 462, and USB port 464. Finally, SouthBridge 458 is coupled with the flash memory where BIOS 466 is located. In the illustrated embodiment, the mobile host 14 includes fewer peripheral components than the fixed host. Those skilled in the art will appreciate that any number of configurations are possible.

Although the embodiment described in connection with FIG. 4 utilizes a front side bus architecture, those skilled in the art will understand that the present invention can be implemented with other board level architectures. For example, the present invention can also be implemented to be connected to a board architecture using HyperTransport ™ over a high speed wireless connection. In this embodiment, at least one computing device is designed with HyperTransport technology that acts as a fully integrated front side bus as shown generally in FIG. 3. In this embodiment, the NorthBridge-SouthBridge structure is excluded.

5 illustrates some features of the invention at a more conceptual level. As shown, the high-speed wireless bus 16 forms a wireless bridge between the fixed host computing device 12 and the mobile host computing device 14. Each of these devices exposes a wireless bus interface, which provides access to its core or essential resources. Thus, for example, the core resources of the fixed host 12 are made available to the mobile host 14. As used herein, this "critical resource" refers to any of a fixed host processor, RAM, and nonvolatile storage. Similarly, key resources of the mobile host 14 are exposed through its wireless bus interface. Because each wireless bus interface connects directly through the front side bus of the computing device, these resources become available once the connection is established and the credentials of the computing device are verified.

Note that although known techniques currently allow some connectivity between computing devices, this may not achieve the benefits of the present invention. For example, known server technologies allow a user to "hot plug" additional processors over the front side bus. However, the feature only provides additional processing capacity to the server of interest. Current docking station and replicator technologies likewise cannot provide the benefits of the present invention because these technologies at most interconnect the docked system and the SouthBridge circuitry of the docking system. Therefore, the latter technique cannot provide for sharing of key resources of individual computing devices.

6 shows a process for establishing a high speed wireless connection from a standpoint of a mobile host attempting to establish a connection with a fixed host. For clarity, FIG. 6 focuses on aspects of embodiments of the present invention and omits some details that are familiar to the prior art.

In step 610 of the flowchart, a computing device, such as the mobile host computing device 14 shown in FIG. 1, begins in step 610 and indicates that one or more other UWB capable computing devices are within its transmission range. When 14) detects, step 612 is reached. As will be appreciated by those skilled in the art, such detection can be performed by any suitable connection module. In this step, the mobile computing device 14 establishes a physical wireless connection with the detected one or more other computing devices (in this case, the fixed host computing device 12). Once a wireless connection is established, in step 614 the mobile host computing device 14 determines whether connectivity with a fixed host device can occur over a high speed wireless bus. To perform this step, the mobile host device 14 issues its credentials. Similarly, the mobile host 14 receives credentials from a fixed host regarding the possibility of connecting. Based on the credentials exchanged between computing devices, the method then proceeds to step 616 to determine whether a connection has been established. Otherwise, the method ends at step 618.

On the other hand, if the mobile host determines that a connection can be established during step 616, the method proceeds to next step 620 and receives a list of available resources from the fixed host 12. In the next step 622, the mobile host 14 extends the available resources to the system. This may include, among others, the further allocation of volatile memory, the expansion of logical disks or nonvolatile memory, and the use of coprocessors. By allocating the available resources, as shown in step 624, the mobile host device 14 provides a user with a single logical computing entity having a combined resource of mobile and fixed hosts. That is, the mobile host device will appear to the user as if it contains both available resources of both physical devices.

In the preferred embodiment, the operating system 14 of the mobile host device assumes control of the available resources and assigns tasks to the resources. In this embodiment, the resources allocated to the created logical entity function under the control of a single operating system.

During operation of a single logical host device, as shown in step 626, the mobile host device 14 may receive an interrupt request from the fixed host 12. If an interrupt request is received, the method proceeds to step 628 to service the request. This may include, among other things, reconfiguring a logical unit when some resources become unavailable. The operating system running on the mobile host handles these requests in a logical way so that the user is not aware of any impact. The method then continues until another interrupt request is issued. Similarly, the mobile host device may issue an interrupt request to the fixed host device, for example, when a change in resource state occurs.

In another embodiment of the present invention, a high speed wireless connection may be established between multiple computing devices. In addition, multiple parallel wireless communication channels may be used to establish a connection between computing devices.
